My invention relates to smoking pipes and has special reference to means for condensing and trapping the nicotine carried by the smoke into the pipe. The objects of my invention are to provide a device which will automatically cool and condense the nicotine from the smoke; which will collect or trap the said nicotine; from which the liquid nicotine may be readily removed; and which l0 is cheap to manufacture.

I attain these and other objects by the devices and arrangements illustrated in the accompanying drawing, in which- Figs. 1, 2 and 3 are vertical sections of three forms of my invention; Fig. 4 is a side elevation of the pipe stem shown in Fig. 3; Fig. 5 is a similar view of the cap therefor; FigA 6 is a section of the end of such a pipe stem, showing the cavity closed by a plug; and Fig. 7 is a front view of the pipe bowl.

Similar numerals of reference refer to similar parts throughout the vseveral views.

My invention is equally well adapted for use in smoking pipes of various types, two forms of which are illustrated in the drawing. The pipe comprises a bowl portion, having a bowl 1 and an integral stem holder 2, into which the pipe stem tits as hereinafter described. The bowl 1 is preferably made with a flat bottom 3 so that the bowl will remain in an upright position when placed on a table. The stem holder 2 is provided with a hole 4 extending deeply therein and adapted to hold the stem and the nicotine trap, as hereinafter described. This hole 4 may extend entirely through the stem holder 2, as shown in Fig. 1, orV it may eX- tend almost therethrough, as shown in Figs. 2 and 3. The end of this hole 4 (Figs. 2 and 3) is provided with two ventilation openings 5 and', which are so positioned as to Vcause a circulation of cold air to enter at the base oit the hole 4 and pass upward, around the hereinafter described condensing trap, and then out by the hole 6 through the side of the part 2 of the pipe. The smoke passage 7 leads from the base of the bowl 1 to the upper or outer part of the hole 4, said passage 7 being easily reached from the open end of the hole 4 for the purposes of cleaning it out.

The pipe stem 8 is provided with an eX- tension `9 which enters the hole 4. In Figs. 1 vand 3, this extension 9 fits tightly in the outer part of the said hole 4 and is provided with a central smokepassage 10 and with a 55 lateral smoke passage 11, adapted to register with the above-described smoke passage 7 of thebowl. This extension 9 fitstightly in the hole 4 and does not'admit any air through the surface of Contact between the parts. A second extension 12, of smaller diameter than the part 9, and smallerin diameter than the hole 4 in which it lies,`passes from the end of the first extension 9 and is provided with an enlarged cavity 13, extending from the main central smoke pipe or passage 10. In Fig. 6 this cavity 13 is closed by means of a suitable removable plug 14; in Figs. 3, 4 and 5 it is closed by a small removable cap 15; and in Fig. lit4 is closed by a metal tubular 70 container or trap 16, removably mounted on the end of the shorter extension 12.

In the form of my invention illustrated in Fig. 2, the pipe stem 8 is provided with a short` extension 17 on to which the metal 75 tubular container 18 is removably secured, and Vthe upper part of said container 18 fits tightly in the hole 4 and is provided Ywith a smoke opening 19 registering with the smoke passage 7 of the bowl 1. In this case the 80 lower part 20 of the container 18 is reduced in diameter at a point well below the said opening 19.

Thus it will be seen that the inner or lower end of the pipe stem, or of its extension, is, in eachy case, ofsmaller diameter than the hole 4 in which it lies and that an annular circulation chamber is thus formed around it, said chamber receiving air freely either through the open end of the hole 4 (Fig. 1) 9'0 or through the end air hole 5 (Figs. 2 and 3) and discharging it from the air hole 6, thus cooling the lower end of the stem and causing the nicotine vaporto condense in the cavity or trap 13 or in the tube 16 or 18, from which it may readily be removed whenever desired.

' It is evident from the aboveA and from the drawing that this pipe accomplishes its re- 10o sults while maintaining the ideal of eXtreme "simplicity of construction, thereby keeping its cost of manufacture to within a very close figure as compared with the ordinary smoking pipe of like material and type, and that 5 the bowl will not collect nicotine but will be kept dry, and that all the nicotine and other moisture will collect in the cooled condensing cavity, as above described.-

Itis also evident that many variations may be made in the form, shape, or arrangement of the several parts of my invention without departing from its spirit, as outlined in the appended claims.

Having, therefore, described my invention what I claim and desire to secure by Letters Patent, is

1. A smoking pipe having a bowl, stem holder, and smoke passage, the stem holder having a long hole therein adapted to receive the stem and extending relatively ar beyond the smoke passage; a'stem fitting' yin the outer end of the hole and having a central smoke passage extending from end to end and connecting with the smoke passage leading to the bowl; a` condensing chamber connected to said central smoke passage at a point beyond said smoke passage leading to the bowl, and lying in. the inner end of the Ihole in the stem holder, buty of small diameter, thereby forming an annular air chamber in the inner end of said stem holder; and air openings at the ends of said annular chamber adapted to permit the'circulation of air I around said condensing chamber.

1 35 2. A smoking pipe comprising a bowl por--v v,tion and a stem portion, said bowl portion having an elongated stem-receiving hole and a: connecting passage leading from the bowl to the outer part of said stem-receiving hole;

40 said stem portion having a passage from end to end and tting in the outer end of said `stem-receiving hole and having a lateral {passage registering in said itted part with said connectingpassage, and extending in said hole beyond said itted part at a reduced diameter to form a condensing chamber of the inner end of said passage; a removable closure for the end of said condensing cham ber; and said bowl portion having air inlet and outlet holes adapted to permit circulation of air around said condensing chamber.
